United States Patent 3,138,045 CALKING AND YARNING IRON John R. Ourada, 222 /2 Park Ave., Omaha, Nebr. Filed Feb. 19, 1962, Ser. No. 174,110 4 Claims. (Cl. 7847) The present invention relates to tools used by plumbers for connecting lengths of sewer pipe where a plain end of one piece of pipe is secured in a bell on the end of another piece of pipe, and in particular a substantially semi-circular arm having an elevated anvil on the intermediate part, a yarn rope receiving notch in the extended end, a tamping finger removably mounted at a point spaced inwardly from said extended end, and a handle on the end opposite to said extended end, whereby with an end of a calking rope retained in the notch the rope may be passed around a vertically disposed pipe, fed into an open area between the pipe and bell, and tamped by the finger to rigidly hold the plain end of the pipe in the bell.

The purpose of this invention is to facilitate connecting ends of sewer pipe where the pipe is positioned close to a wall, in a corner, or in a partition where it is difficult to reach or pass the hands around the pipe.

Although conventional black iron sewer pipe is the most common pipe provided with bell joints bells are provided on at least one of the ends of pipe used for other purposes. Where such pipe is located against or close to a fixed wall, or in a corner, or enclosed in a partition, it is very difficult to pass the oakum yarn completely around the pipe. It is also diflicult to tamp or pack lead against the yarn in the bell, and as it is essential that a tight joint be obtained various types of tools have been used for driving the lead into the bell.

With these thoughts in mind this invention contemplates an arm curved to extend at least'half way around a pipe whereby oakum yarn may be easily passed around the pipe. The arm is also provided with a finger positioned parallel to the axis of the pipe, whereby with the finger extended into the bell oakum yarn and also hot lead are packed in the bell by striking the arm with a hammer, or the like.

The object of this invention is, therefore, to provide a tool for plumbers which makes it possible to pass packing around a pipe without passing the arm completely around the pipe.

Another object of the invention is to provide an iron for packing lead in a bell around a pipe in which a finger of the iron may be driven against the lead by striking the arm with a hammer or the like.

Another important object of the invention is to provide a plumbers tool for positioning and packing yarn and the like in a bell joint in which a packing finger of the tool is removable and replaceable, so that fingers of different lengths may be used.

A further object of the invention is to provide a tool for packing oakum yarn and the like in a pipe bell joint in which a finger positioned normal to an arm of the tool is removable to facilitate packing and shipping the tool.

A still further object is to provide a calking and yarning iron for making joints in pipe having bell ends in which the iron is of simple and economical construction.

Other and further objects and advantages of the present invention will be apparent from the following detailed description, drawings and claims, the scope of the invention not being limited to the drawings themselves as the drawings are only for the purpose of illustrating a method by which the principles of this invention can be applied.

Other embodiments of the invention utilizing the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.

FIGURE 4 is a section through the outer end of the arm of the calking and yarn applying tool taken on line 44 of FIGURE 1, with the parts shown on an enlarged scale, and illustrating the mounting of the finger on thevarm.

FIGURE 5 is a cross section through the finger mounting shown in FIGURE 4, taken on line 55 of FIG- URE 4.

FIGURE 6 is an end elevational view of the arm of the tool showing a modification wherein a short finger, such as used for tamping hot lead in a bell joint, is mounted on the end of the arm.

FIGURE 7 is a perspective view illustrating the use of the tool in applying yarn to a bell of a pipe joint.

While one embodiment of the invention is illustrated in the above-referred-to drawings, it is to be understood that they are merely for the purpose of illustration and that various changes in construction may be resorted to in the course of manufacture in order that the invention may be utilized tothe best advantage according to circumstances which may arise, without in any manner departing from the spirit and intention of the device, which is to be limited only in accordance with the appended claims. And while there is stated the primary field of utility of the invention it remains obvious that it may be employed in any other capacity wherein it may be found applicable.

In the accompanying drawings, and in the following specification, the same reference characters are used to designate the same parts and elements throughout, and in which the numeral 10 refers to the invention in its entirety, numeral 12 indicating an arcuate, substantially semi-circular arm having a handle 14 on one end, an anvil 16 on the intermediate part, a notch 18 in the extended end for holding the end of oakum yarn 20, and recesses 22 and 24 in the upper and lower edges for receiving lugs 26 and 28 of a finger 30.

The upper portion 32 of the finger 30 is provided with an opening 34 that is positioned over a stud 36, and the finger is secured on the stud and arm by a lock nut 38.

In the design shown in FIGURE 4, the finger 30 extends downwardly to the point 40, so that it will reach packing 42 in a bell 44 of a pipe 46. The open end of the bell is sealed by hot lead 48, and when the tool is used for tamping the lead the finger 30 is removed from the arm and a short finger 50, as shown in FIGURE 6 is clamped on the stud. The finger 50 is provided with lugs 52 and 54, similar to the lugs 26 and 28 of the finger 30. The fingers may be provided in different lengths, and the radius of the arm 12 may be changed to accommodate pipe of ditferent sizes.

The arm 12 is provided with a mounting shank 56 which extends from the end 58 into the handle, and the end of the handle into which the shank extends is provided with a ferrule 60.

The notch 18 in the extended end of the arm 12 is provided with sloping surfaces 62 and 64 which converge to hold the end of a strand of yarn as the yarn is passed around a pipe, as illustrated in FIGURE 7.

As best seen in FIGURE 4, the upper side of the lower finger lug 28 provides an abutting impact surface 53 which is disposed in abutment with a lower impact surface 55 3 of the arm 12, the surface 55 also being an inner end of the lower notch 24.

The abutting impact surfaces 53 and 55 are sufficiently horizontal and of sufficient area for transferring the downward motion of the arm 12, when struck with a hammer, to the finger 30 with mechanical soundness.

Operation With the parts assembled as illustrated and described, and with oakum yarn retained in the notch 18 in the end of the arm, as shown in FIGURE 7, the yarn is packed by the finger 30 in the bell and around the pipe 66, as shown in FIGURE 3. With the yarn in place hot lead is poured in the open end of the bell, and the lead is tamped by the short finger 50, the tamping being accentuated by striking the anvil 16 with a hammer, as indicated by the broken lines 68. By this means the yarn and lead may be worked into the space between the pipe and the bell, as shown in FIGURE 3.

From the foregoing description it is thought to be obvious that a calking and yarning iron constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as claimed.

Having now described the invention that which is claimed to be new and desired to be procured by Letters Patent, is:

l.
